利用java8 stream流将一个对象集合转换成另一个对象集合

//需要字段名一致 


        List<UserCheckData> userCheckDataList = null;
        
        List<UserCheckPO> list = userCheckPORepository.findAll();
        if(CollectionUtils.isNotEmpty(list)){
            userCheckDataList = list.stream().map(userCheckPO -> {
                UserCheckData userCheckData = new UserCheckData();
　　　　　　　　　　//将userCheckPO拷贝给userCheckData
                BeanUtils.copyProperties(userCheckPO, userCheckData);

                return userCheckData;
            }).collect(Collectors.toList());
        }

　　  // 从数据库中查询出的对象集合
        List<OperationStation> operationStations = operationStationJoinMapper.selectJoinByExample(example);
        // 判端是否为空
        if (CollectionUtils.isNotEmpty(operationStations)) {
            // 进行拆解封装
            List<StationDictVO> stationDictVOS = operationStations.stream().map(operationStation -> {
                StationDictVO stationDictVO = new StationDictVO();
                stationDictVO.setStationId(operationStation.getStationId());
                stationDictVO.setStationName(operationStation.getStationName());
                return stationDictVO;
            }).collect(Collectors.toList());
　　}
